There are a couple fuses and relays that control the DRL's in your truck. Of course start basic and be sure the bulbs are good, after that you will need to do some testing to see what the problem is.

See the attached guides/diagrams below for information on how to test wiring and relays.
Check back in with what you find

Hello,

My DRL has suddenly stopped working. I have a 2003 Ford F150 XL. The headlights both work and both fuses (in the cab and under the hood) are fine. What else can I check from here. What would cause them to suddenly stop working?

Thank you

Check and test the DRL module.
